What does a differential white cell count tell you?

A differential blood count gives the relative percentage of each type of white blood cell and also helps to reveal abnormal white blood cell populations (eg, blasts, immature granulocytes, and circulating lymphoma cells in the peripheral blood).

What does high white blood cell differential mean?

There are many reasons your blood differential test results may be outside the normal range. A high white blood cell count may indicate an infection, immune disorder, or allergic reaction. A low count may be caused by bone marrow problems, medication reactions, or cancer.

What does white blood cell test show?

A WBC count can detect hidden infections within your body and alert doctors to undiagnosed medical conditions, such as autoimmune diseases, immune deficiencies, and blood disorders. This test also helps doctors monitor the effectiveness of chemotherapy or radiation treatment in people with cancer.

What is the difference between a differential white blood cell count and a total white blood count?

A white blood cell (WBC) count measures the number of white blood cells in your blood, and a WBC differential determines the percentage of each type of white blood cell present in your blood. A differential can also detect immature white blood cells and abnormalities, both of which are signs of potential issues.

What happens when you have a low white blood cell count?

White blood cells are produced by your bone marrow to help your body fight infection. If you have fewer than normal white blood cells, you have a higher risk of getting an infection. When you have a low white blood cell count, your immune system isn’t working as well as it should.

An abnormally raised white blood cell count is not a disease condition, but can point to another underlying cause such as infection, cancer or autoimmune disorders. An abnormally high white blood cell count should always be considered for its possible causes.

How do you count a WBC differential?

To determine the differential, a drop of blood is thinly spread over a glass slide, air dried, and stained with a Romanofsky stain, most commonly the Wright or May-Grunewald-Giemsa technique. Two hundred cells are then counted and classified.

When performing a differential cell count how many leukocyte are counted?

Differential cell counts are usually performed on 100 to 200 cells and are expressed as percentage values.

What does a WBC differential indicate?

WBC differential results indicate the number and/or the percentage of each type of white blood cell that is present in your sample of blood at the time of the test.

What is the correct total WBC count?

Normal Results The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens.

Why do we perform manual WBC count?

The manual differential white blood cell count is performed to determine the relative number of each type of white blood cell present in the blood. A study of red blood cell, white blood cell, and platelet morphology is also performed.

How do I interpret my white blood cell count?

White blood cells (WBCs) A healthy person has an ANC between 2,500 and 6,000. The ANC is found by multiplying the WBC count by the percent of neutrophils in the blood. For instance, if the WBC count is 8,000 and 50% of the WBCs are neutrophils, the ANC is 4,000 (8,000 × 0.50 = 4,000).
